Description
- The present devices relate generally to improving fixation of acetabular cups, and more particularly to preventing bio matter (such as soft tissue and fatty deposits) from contacting an acetabular shell during delivery through a wound until just prior to impaction.
- In surgery, it is possible to contaminate an acetabular shell with bio matter, soft tissue, and fatty deposits prior to and during impaction. Each time an acetabular cup is inserted into a body cavity, soft tissues and bio matter can build up on portions of the acetabular cup and become stuck. If these materials gather onto or bind to a porous outer coating of the cup, it could adversely affect bone in-growth and initial "bite" and "fixation". If these materials gather on a smooth inner surface of the cup, it could adversely affect subsequent taper-locking between the cup and a liner. Connections between acetabular cups and liners are generally designed with tight tolerances to form a tight fit. Bio-matter can compromise such a tight fit. The devices aim to provide a novel and unique apparatus and method of preserving the porosity of an acetabular cup during insertion into a body cavity.
-
US 2007/100464 AA Figure 1 . This reference does not disclose use with acetabular cups, and the sheaths shown in this reference teach away from providing a means for acetabular cup penetration as the disclosure is used to protect surfaces proximal to the wound. - Other related art teaches soft tissue protection devices which may be placed over a wound or within a wound. These devices are placed onto or into the wound prior to advancement of a medical device. Such a device only protects the soft tissue covered by the device from damage. The closest prior art is disclosed by
EP 0 650 706 . - The aforementioned needs are satisfied by several aspects of the devices.
- An aspect of the invention provides an acetabular cup and sheath assembly comprising a sheath and an acetabular cup. The sheath is configured to receive the acetabular cup within the sheath. The sheath and acetabular cup together are configured to pass through a surgical wound toward an implantation site. The sheath further comprises a penetration structure for passing the acetabular cup through the sheath when the acetabular cup is proximately close to an implantation site.
- Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating certain embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
- The accompanying drawings, which are incorporated in and form a part of the specification, illustrate the embodiments of the present invention and together with the written description serve to explain the principles, characteristics, and features of the invention. In the drawings:
-

FIG. 8 illustrates yet even another embodiment; -
FIG. 9 illustrates another embodiment; -
FIG.10 illustrates yet another embodiment; -
FIGS. 11a-11c illustrate a method of packaging an embodiment; and -
FIGS.12a-12e illustrate a method of using an embodiment. - The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.
- The device provides, in part, an improved method of inserting an acetabular cup (i.e., shell) into a body cavity. The method utilizes a sheath that temporarily encloses the acetabular cup during insertion into a body cavity. The sheath protects the cup from bio-matter which could compromise a good taper lock with a liner, or a good initial scratch-fit with bone.
- It is preferred that the sheath be sterile-packed with the acetabular cup. The sheath may be incorporated as an integral or separate part of the acetabular cup packaging, or may have a separate part number and used as a disposable instrument. Furthermore, the sheath may be provided as a non-disposable instrument which is configured for multiple sterilizations. The sheath should be somewhat flexible at portions to allow an acetabular cup to penetrate or protrude from one end; however, the sheath may also incorporate more rigid portions at other areas for strength, conformity, and to better push surrounding soft tissues radially-outward away from the acetabular cup. Sheaths may be made so as to be capable of universal use across a variety of differently-sized acetabular cups.
- The usefulness of the sheath and methods associated therewith is not limited to acetabular cups. The present device may also be advantageously used with acetabular liners, cages, and/or augments alike such that a surface away from the wound must be passed through the sheath.
-
FIGS. 1a-1c illustrate sheaths used in the prior art for hip applications. The sheath is disposed on a proximal end of an implant and is used to protect a taper lock. The sheath is not penetrable by the implant, and is meant to roll off the implant. The embodiments of the present invention, however, include a port through which the implant must pass in order to properly position the implant in the bone. -
FIG. 1d illustrates the problems associated with prior art methods. Conventionally,acetabular cups 10 are inserted using a positioner/impactor 12 into a body cavity wound 20 without any protective sheath. Thecup 10 is passed through thewound 20 across fatty tissue andsoft tissue 22 until thecup 10 is positioned over the preparedacetabulum 24. As thecup 10 is passed, the fatty tissue andsoft tissue 22 may brush against the porous surface of the implant. Consequently, fatty tissues andsoft tissues 30 cling to the rough, porous, or frictional surfaces of theacetabular cup 10, which are purposely designed for bony ingrowth and initial fixation. With portions or all of the rough, porous, or frictional surfaces "gummed up" by bio-matter, bone ingrowth and the initial fixation "bite" of theacetabular cup 10 is compromised. -
FIG. 2 illustrates one embodiment of a cup-shapedsheath 30 for anacetabular cup 10. The sheath incorporates a means for acetabular cup penetration comprising asingle slot 32. Theslot 32 is sized such that thecup 10 is retained within thesheath 30 as theshell 10 andsheath 30 are passed through the wound. Once thecup 10 reaches the implant site, then thecup 10 may be pushed through theslot 32 by deformation or tearing of theslot 32 andsheath 30. -
FIG. 3 illustrates another embodiment of a cup-shapedsheath 40 for anacetabular cup 10. The sheath incorporates a means for acetabular cup penetration comprising two generallyorthogonal slots 42. While the slots are generally orthogonal, the slots may otherwise by oriented relative to each other such that the give an appropriate amount of clearance to thecup 10 as it passes through thesheath 40. By using multiple slots crossing each other, it may be possible to have thinner or shorter slots than a single slot orientation. -
FIG. 4 illustrates another embodiment of a cup-shapedsheath 50 for anacetabular cup 10. The sheath incorporates a means for acetabular cup penetration comprising at least oneaperture 52. While theaperture 52 is generally oval, other aperture shapes for passing the shell through the sheath may be used such as a round, square or triangular apertures. The size of the aperture should be smaller than the shell but large enough so that the cup may pass through the aperture. Smaller aperture sizes may minimize the contact between the cup and the soft tissue and thus minimize the amount of bio-matter on the porous surface. -
FIG. 5 illustrates another embodiment of a cup-shapedsheath 60 for anacetabular cup 10. Thesheath 60 incorporates a means for acetabular cup penetration comprising several circumferentially-spaced, radially-extendingslits 62. The slits may be simple cuts through thesheath 60. Such asheath 60 may preferably be made of a less flexible material so that the triangular wedges made between the slits may retain the shape of the bottom of thesheath 60 and may better retain thecup 10 from passing through thesheath 60 prematurely. -
FIG. 6 illustrates another embodiment of a cup-shapedsheath 70 for anacetabular cup 10. Thesheath 70 incorporates a means for acetabular cup penetration comprising a reduceddiameter end 72. Theend 72 may be extruded, but again the size of the opening should be less than the size of thecup 10 so that thecup 10 cannot pass through thesheath 70 without some amount of force between thesheath 70 and thecup 10. -
FIG. 7 illustrates another embodiment of a cup-shapedsheath 80 for anacetabular cup 10. Thesheath 80 incorporates a means for acetabular cup penetration comprising at least oneflap 82. The flap may have a reduced width connection portion to facilitate movement and passage of theacetabular cup 10. Theflap 82 may be preformed with the sheath using perforations that can be severed after the acetabular cup has passed through the body cavity and is ready for bony contact. Thetab 82 may also be cut through the bottom of thesheath 80 and made from a less flexible material such as thesheath 60 ofFIG. 5 . -
FIG. 8 illustrates another embodiment of a cup-shaped sheath90 for anacetabular cup 10 having aslot 92 for passing thecup 10. The sheath incorporates at least oneremoval structure 94 of thesheath 90 from a body cavity. Theremoval structure 94 may comprise a tab, a hole, an engagement lip, or any other structure which can be engaged to easily remove thesheath 90 from a body cavity. Theremoval structure 94 may be engaged by the surgeon's fingers, or may be part of a mechanism attached to the impactor which would pull thesheath 90 away from the porous surface of thecup 10. -
FIG. 9 illustrates another embodiment of a cup-shapedsheath 100 for anacetabular cup 10. Thesheath 100 incorporates a means for acetabular cup penetration comprising aperforation pattern 102. The pattern may be in a pizza-slice configuration as shown, in a simple line configuration, or in a flap configuration as shown inFIG. 7 . Theperforations 102 may allow better isolation of the porous surface from the soft tissue than the embodiments of slots or shapes, but may require more force to push thecup 10 through thesheath 100. Also, complete removal of the sheath 100 (including the tabs at the perforations) may require additional visual acuity during the replacement surgery. -
FIG.10 illustrates another embodiment of a cup-shapedsheath 110 for anacetabular cup 10. Thesheath 110 incorporates a means for acetabular cup penetration comprising aperforation shape 112. The shape may be in any form and not to be limited to what is shown. For instance, a perforation shape may be comprised of one or more of a triangle, oval, star, polygon, or other multi-sided geometric shape having spline curves. - While the embodiments described above have disclosed many individual forms for the penetration means, it is possible to combine these forms into a single form. For example, a shape similar to the example shown in
FIG. 4 may also have a slot or slit extending through remaining portions of the sheath. Such embodiments may allow additional flexibility in the type of material used and the amount of force necessary to push the cup through the sheath. -
FIGS. 11a-11c illustrate a method of packaging one embodiment. Asheath 100 is packaged with anacetabular cup 10. The assembly is packaged (e.g., using a box orcontainer 120 shown inFIG. 11c .) and then sterilized according to conventional methods. Theperforation pattern 102 may be any of the penetration means disclosed herein. -
FIGS. 12a-12e illustrate a method of using an embodiment. A packagedsheath 100 andacetabular cup 10 assembly is removed from a container 120 (FIG. 12a ). Aninserter instrument 12 is inserted into the acetabular cup 10 (FIG. 12b ). Theinserter 12 inserts theacetabular cup 10 through a body cavity 20 (FIGS. 12c-12d ) to aprepared acetabulum 24 such that thesheath 100 shields the acetabular cup from contact with "gummy" bio-matter 22 which can clog the outer porous structure of theacetabular cup 10. At the bottom of the body cavity, theacetabular cup 10 protrudes from or penetrates through a means for acetabular cup penetration (FIG.12d ).Flaps 130 on thesheath 100 part to allow the cup to pass through thesheath 100. Finally, thesheath 100 is removed or otherwise generally displaced from theacetabular cup 10, thecup 10 is impacted, and both thesheath 100 and theinserter instrument 12 are removed from thebody cavity 20. - In some embodiments, it may be necessary to change the sizes, shapes, lengths, and widths of the slits, slots, flaps, shoulders, etc. to accommodate various shapes and sizes of acetabular cups, shells, augments, cages, etc. and to allow easy penetration of the acetabular cup through the sheath during impaction.
- The sheath may be disposable, flexible, colored, non-colored, opaque, transparent, translucent, lubricated, non-lubricated, anatomically-shaped, non-anatomically shaped, cylindrical, implant conforming or cup-shaped, and may have various cross-sectional types. The sheath may be flanged at the open end and configured to rest on bony portions of the acetabular rim, or may be un-flanged to facilitate insertion and withdrawal. The thickness of the sheath may vary. Means provided to the sheath to allow cup penetration can be configured in different ways as would be expected by one having an ordinary skill in the art. Indicia may be provided on the sheath, such as arrows, trademarks, instructions (e.g., for insertion, disposal, orientation, patient or physician info, model number, product number, identification, etc.), or other forms of indicia. Indicia may be moulded in or provided through the usage of inks or dyes. Sheaths may be incorporated with other instruments as an integral unit, or sheaths may be provided with means for effectively facilitating removal from a body cavity - such means may amount to apertures, locking mechanisms, tangs, shelves or ledges for engagement by a tool, etc. In some instances, it may be desirable to incorporate the sheath with a liner inserter guide as one integral unit such as the inserter guide disclosed in co-pending application "Acetabular Liner Inserter Guide"
PCT US2008/055323 . - While the sheath has been described as having a formed bottom portion, the top portion may also be similarly formed as opposed to open. This may help to further protect the cup from bio-matter and may further allow the surgeon to reposition the sheath and cup by moving the sheath and cup out of the wound. In packaging the cup, the cup would then pass through one side of the sheath in order to get the cup within the sheath and then be passed through the other side during implantation.
- As various modifications could be made to the exemplary embodiments, as described above with reference to the corresponding illustrations, without departing from the scope of the invention, it is intended that all matter contained in the foregoing description and shown in the accompanying drawings shall be interpreted as illustrative rather than limiting. Thus, the breadth and scope of the present invention should not be limited by any of the above-described exemplary embodiments, but should be defined only in accordance with the following claims appended hereto.
- The embodiments may improve initial bony fixation by preventing clogging of porous or frictional surfaces on an acetabular cup during insertion into a body cavity. The embodiments may further reduce the risk of liner mal-alignment by keeping most of the inside of the acetabular cup free from debris and soft tissue. The embodiments may even further decrease the risk of an acetabular liner dislodging from its acetabular shell by ensuring that all mating portions between a liner and shell are free from bio-matter.
